VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 381,843, dated April24, 1888.

Application filed March 2, 1887. Serial No. 229,405. (No model.)

To all whom it may concern:

Be it known that I, FORDYOE ALLEN LY- MAN, of Cleveland, in the countyof Ouyahoga and State of Ohio, have invented certain new and usefulImprovements in Vapor-Burners; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in vapor-burners; and it consistsin a burner having an enlarged supply-pipe filled with packing material,a rotating heating-chamber and lighting-cup, and movable delivery-pipesfor supplying vapor to supplemental burners, all as hereinafter fullydescribed and claimed.

The object of my invention is to place upon the staud-pipe aheating-chamber which has the lighting-cup secured thereto, and whichchamber can be turned through a portion of a circle carrying thelighting-cup with it; to provide the lighting-cup with stops to limitthe distance the lighting-chamber shall be turned upon the stand-pipe,and to provide the lighting-cup with two wells, which are connectedtogether by means of a perforation through the partition which separatesthem.

Figurel is aside elevation of avapor-burner stove embodying myinvention, the stand and supply pipes being in section. Fig. 2 is a sideelevation of the central generatingburner and its attachments, taken atright angles to Fig. 1. Fig. 3 is a Vertical section taken down throughthe burner. Fig. 4 is a detached view of the heating-chamber andlightingcup alone. Fig. 5 shows a generating-chamber from which thepipes rise vertically. Figs. 6 and 7 are details of the lighting-cup.

A represents the framework of the stove; B, the vertical supply-pipeleading from the tank; 0, the horizontal supply pipe, and D the verticalstand-pipe for the central generating-burner. The supply and stand pipesC D are made much larger than is usual in the construction ofvapor-burner stoves, and both of these pipes are filled with a suitablepacking material of any kind, but preferably of small gravel.

In vapor-burner stoves where the gas is generated by a single generatorof sufficient capacity to supply several burners with gas, when such agenerator is not supplying the other burners, but at the same time iskept heated by the generating fiame ready for use, there mustnecessarily be an accumulation of gas, and a pressing or forcing back ofthe liquid fuel into the tank, and the heat follows back through thestand and supply pipes. The trouble heretofore has been to prevent theburners from puffing when the gas for one or more burners would beturned on. Where small stand and supply pipes have been used, the vaporextends back into the small spaces afforded by these pipes and ispressed forward by the liquid fuel, which, coming in contact with theheated portion of the generator, causes a sudden expansion of gas, andthis expansion causes the pufling of the burners. To prevent thistrouble, I enlarge the supply-pipe in proportion to the size or capacityof the generator to be used and fill it with a continuous packing ofsuitable material-such as small pebbles-=-from the stand-pipe orgenerator to any desired distance outward, so that when the generator isat its greatest heat the gas will not extend beyond the packing. Whenthe burners are lighted, the supply-pipe being large, the movement ofthe fuel is slow in comparison to what it is in a smaller supplypipe,the temperature will be kept uniform, and the liquid will move on intothe generator without encountering sudden changes of temperature. Theenlarged supply-pipe absorbs the heat from the generator when the gas isnot being used, and thus forms a storage place for the accumulatedgas.This enlarged supply or retort pipe may be placed in a horizontal orvertical position and still be within the meaning of my invention.

Placed upon the stand-pipe for the central generator is the rotatingheating-chamber F, which is provided with a tube, 2', in one side forthe admission of the vapor which is to be used in heating the generator,and which is provided with small openings Gr through its bottom for theadmission of air to support combustion at the top of the generator forheating the generating-chamber. This chamber F is supported looselyuponthe stand-pipe by means of a collar, E, secured thereto, so that ICOit can be rotated partially around and thus move the tube i out of linewith the casing of the valve H, when the lighting-cup I is to bebroughtintouse. Thedelivery-pipeyprojects out from one sideof thechamber L and extends outward and downward and has the valve H passedthrough its lower end for the purpose of controlling the supply of vaporthrough the inductiontube t. This lighting-cupl is secured to therotating heating-chamber F, and when the chamber is moved this cupswings around through an .arcof a circle, as shown by dotted lines. Thiscup I is divided by the vertical central partition J into two wells, atc, the outer one of which, when the cup is brought into use, comesdirectly under the valve H, while the inner well comes undertheheating-ehamher, so as to ignite the vapor which escapes at the topof the chamber. These two wells are connected together by a smallopening, 9, in the bottom of the vertical partition, so'that the flamecan pass from the outer to the inner well when the fluid in the cuphasbeen nearly consumed. The lighting-cup and the heatingchamber aremoved into the position indicated by dotted lines in Fig. 4, and thevalve controlling the escape-orifice of the duct 3 is opened to allowthe fuel to escape. The stream of escaping oil strikes the partition Jand fills the chambers a and c, flowing into the latter from the formerthrough the opening 9 in the partition. The valve is closed and the oilin the well a is then ignited and the heat thus generated vaporizes theoil in the duct 3 The lighting-cup and heating-chamber are then turned,so that the inlet i aligns with the valveorifice of the duct y. The oilin the well a having by this time burned sufficiently low for the flameto pass through the opening. 9, the oil in the well 0 is automaticallyignited. The valve-orifice of the duct y is then opened, allowing vaporto escape into the heating-chamher, and thence through the perforationsof this chamber, and the vapor is ignited by the flame from the well 0.The well 0 is made deeper than the well a, so that the oil in the well 0may burn and thus be available after the oil in the well a is exhaustedin supplying the initial flame for vaporizing the fuel in the duct 3This vertical partition J is turned at an angle at its outer end, so asto extend parallel with the outer side of the cup, and thus forms astop, j, for striking against the casing of the valve H and limiting themovement of the cup and the lighting-chamber in one direction.Projecting from the inner side of the lighting-cup is an arm, K, whichhas its outer end turned upward just beyond the center of the orifice tothe lighting-chamber, and which forms the stop to limit the movement ofthe lighting-cup and heatingchamber in the other direction. When theheating-chamber and lighting-cup are moved toward the right until thearm K stops the movement, the valve H stands just opposite the orificeto the heatingchamber, and then the vapor will be discharged directlyinto the chamber for the purpose of being ignited and heati ug thegencratingehamher. When the lighting cup and heating chamber are turnedtoward the left until the flange strikes against the valve H, the cup isin position to be filled with liquid fuel preparatory to starting thegenerator. In this position the blaze is not liable to ignite the vaporin the side tube of chamber when the valve His opened. Theheating-chamber and generator are the same as shown in the Patents No.275,677, dated April 10, 1883, and No. 324,9i7, dated August 26, 1885,heretofore granted to me, and need not be more fully described in thisconnection.

The flame from the heating-chamber impinging against the upper end ofthe standpipe D and against the under side of the gen erating-ehamber L,secured to the top of the standpipe D above the heating chamber,generates the vapor for all of the different buruers,the tube of eachone of which is provided with a valve, M, of its own. Rising from theside of the top of the generatingehamber L is the pipe N, through whichthe vapor for one of the burners issues. This pipe is screw-threaded atits lower end, so that it can be turned in any desired direction, andhas its upper end elbow-shaped and provided with a nipple. By thisconstruction itsgas can bedelivered to conducting-pipesorburnersextending at any angle. Fasteued to the upper outer end of thispipe, inside of the nipple, is the guard-plate O, which serves todeflect the heat rising from the generator toward this pipe N, and thusthe pipe is in the line of the rising currents of heat and is kept hotthereby. As the pipe is thus kept hot by the rising currents of hot air,a plug, instead of a needlevalve, can be used. There maybe any desirednumber of these pipes N rising from the generating-chamber, and each onewill be turned at any desired angle.

The pipe 1? for the central burner rises from the center of thegenerating-chamber and is provided with the flange Q, which projectshorizontally therefrom just below the nipple. Rising from this flangeare the supports R for the inductiontube of the central burner. Thenipple S for each burner is screwed into the pipe and is recessed on itsface around the orifice, so as to prevent the orifice from becomingclosed in case the nipple should be dropped, or while lying around readyto be attached to the other parts of the stove.

Having thus described my invention, I claim- 1. The combination of thestand-pipe, the central generator placed upon the upper end thereof, apipe which conducts vapor from the generating to the heating chamber,the valve which controls the flow of vapor into the heating-chamber, therotating heatingchamber, and the lightingcup which is secured to thechamber, the chamber and the cup being adapted to be moved through anarc of a circle, substantially as shown.

2. The combination of the stand-pipe, the

. chamber shall be turned upon the standpipe,

substantially as described.

3. The combination of the stand-pipe, the central generator placed uponthe upper end thereof, the heating-chamber placed upon the stand-pipe, apipe for conducting vapor from the generating to the heating chamber,and

the lighting-cup provided with the perforated partition J, and the twowells at a, substantially as set forth.

4. The combination of the stand-pipe, the

central generator placed upon the upper end thereof, a support, E,placed on the stand-pipe, the heating-chamber placed upon the standpipeabove the support and resting thereon, and the lighting-cup which issecured to the heating-chamber and projects beyond one side thereof, theheatingchamber and the lightingcup being adapted to be turned through anarc of a circle in relation to the other parts of the burner and to movethe receiving-nozzle of the chamber out of line wit-h the valve,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
